Hello,

we have update Xceed Zip from V3.6 to V4.3. We pack a folder into a new zip file with optional split the new file.

The code below works fine with the old version, but when I try it with the new version I get an ItemDoesNotExistException when I call the EndUpdate Method in the finally block. If a do not use the split option, it is also ok.

Kind regards

Thomas

		static void Main(string[] args)
		{
			Xceed.Zip.Licenser.LicenseKey = "license key";
			ZipEvents events = new ZipEvents();
 
			AbstractFile zipFile = new DiskFile("Test.zip");
			if (zipFile.Exists)
				zipFile.Delete();
 
			AbstractFolder sourceFolder = new DiskFolder(@"C:\Program Files\Xceed Components\Xceed Zip for .NET 4.3");
 
			ZipArchive zip = new ZipArchive(events, null, zipFile);
			
			events.ItemProgression += events_ItemProgression;
			zip.BeginUpdate(events, null);
			try
			{
				// Allow this zip file to span.
				//zip.AllowSpanning = true;
				zip.DefaultCompressionLevel = Xceed.Compression.CompressionLevel.Normal;

Hi Thomas,

If you want to zip the contents of a folder, in this case "C:\Program Files\Xceed Components\Xceed Zip for .NET 4.3", you will need to use the CopyFilesTo method instead. For example:

C#

-----------

sourceFolder.CopyFilesTo(events, "sourceFolder.CopyFilesTo", zip, true, true);

-----------

For more information, you can refer to our online documentation here.

Hello Marc,

yes this works, but with a different result. With CopyTo the folder is included in my zip file, with CopyFilesTo only the files and all subfolders. In this case it is ok for me to create the folder first in the zip and than copy the files to this newly created folder. But why does this method "CopyTo" work in the old version and not in the new one? The documentation you referenced says:

"Do you only want to copy a specific file or folder? Use the CopyTo method."

Thanks

Thomas

Hello Marc,

sorry, I have to take back my statement above. It does not work. If a use only the CopyFilesTo method it is ok, but the result is different. If I create a new folder in the zip files with the same name as the source folder and use the CopyFilesTo method to copy the files in the new folder, I get the same exception as before:

// Zip this folder's contents
AbstractFolder destinationFolder = zip.CreateFolder(sourceFolder.Name);
sourceFolder.CopyFilesTo(events, null, destinationFolder, true, true);

Thanks for your help

Thomas

Hi Thomas,

I have attached a small sample application that shows how to use the CopyTo method with the events to the proper ZipArchive. The sample application uses split zips and should be good enough to incorporate it into your project.
